There was an attempt to port to a recent version of Blender.  When
comparing renderings, the result is close, but not 1:1.  Please check
Mario's reply of 2011 in this very thread
(http://thread.gmane.org/gmane.linux.gentoo.devel/70870).

Hi!


Please excuse bringing up a topic as old as this, again.
Only bringing up half, actually.

 I tried a few more versions now.  While Blender 2.31a still applies the
 reflection texture, Blender 2.32 does not anymore.  At least on
 http://download.blender.org/source/ these two appear as consecutive
 releases.

While doing digital cleaning over here I ran into my patches to make
ancient Blender compile again for Gentoo logo rendering.

I have streamlined those into ebuilds and a dedicated overlay

  https://github.com/gentoo/blender-gentoo-logo-overlay

and filled the void in the Gentoo wiki

  https://wiki.gentoo.org/wiki/Project:Artwork/Artwork#The_blue_.22g.22_logo

with a few words and pointers.

The ebuilds are:

  dev-lang/python/
python-2.2-r8.ebuild

  media-gfx/blender/
blender-2.26.ebuild
blender-2.31a.ebuild

So whoever needs to render Blender files from 2003 again at some point
should find working ebuilds to do that.  Feel free to join keeping them
in good installable shape.

Thanks and best,



Sebastian

Maybe it's time to rethink the logo and get someone to make a more
future-proof SVG? :)

Can't the logo be remade in a more recent version of Blender? Assuming
you can run two separate Blender instances, it would mostly be copying
the poly/vertex values from one to the other.

 My experience modelling in Blender is zero, so it's hard to tell to
 right now me.  From a few cases of remaking vector art from raster
 images in Inkscape, I can imagine that it's difficult to get very close
 in Blender too, if not more.  I hope to have a better answer soon.

 Best,



 Sebastian



This may be a nice opportunity to reach out to the blender community
and ask for assistance and/or training. The information from such
interaction could easily be documented to form a corpus for use in the
future.

If 2.26 still produced good results, 2.37a already does not.  Bisecting
involves fixing compilation for each version.  I stopped getting 2.30 to
compile because it seemed to take forever (longer than fixing 2.26,
2.37a and 2.40 together) and two people had their hands on a port of the
logo to Blender 2.57 by then, one of them still has.  It's too early to
give details.  What I can say is that personally I would want a very
close match in case of a Blender-based replacement, closer than what I
have seen so far.  It still seems possible though.

Best,



Sebastian

It may be.  Of the three variants trying to match the Blender version
that I have seen so far, none is a replacement of equal quality on the
bling scale to my impression.  They feel like tradeoffs, not like the
real thing.  Maybe they try to come too close to the ray-traced
rendering, but I'm not sure if I really want to propose a different
direction either.


 I think such a variant
 would be much more portable and reproducible than blender files.

What I dislike about the idea of moving to a new logo is that we would
give up part of our culture just because we were unable to move it from
past to present to future.  Imagine this dialog:

 A: Hey guys, I noticed you have a new logo?
 B: Yeah, blender rendering changed - so we dropped it.

I don't really want to be B in that dialog.  I see the pragmatic aspect
of moving to SVG but it also has the taste of giving up to me.  To
vercome that taste, a very strong replacement would be needed.

If we replace the Blender g we may also need a substitute for the
red-white Blender gentoo as seen at
http://sources.gentoo.org/cgi-bin/viewvc.cgi/*docroot*/images/gentoo-new.gif
if just for the sake of consistency.

I am wondering what effect the Blender nature of a logo does have on the
capability and will of people to create fan art based on it compared to
an SVG version.  It seems like there is only a handful of 3D Gentoo
wallpapers but does that mean it would have been more with an SVG
version, instead?  On what levels could SVG work as a catalyst?

If we ported the logo to Blender 2.57 now: what can we do to not be
running after Blender rendering changes for all time or to reduce their
impact on us?  Is this a natural cost or an evil one?

Just my 2 cents.

Best,



Sebastian

Well, the concept is to have the same logo but in new format. Of
course, that would require some of professional work to ensure
best-match rendering if even possible.

And I don't think it's really giving up. It's just moving
to the future, putting back good, ol' things in the museum. However,
it'd be still best to fix it.

As I see the concept of a logo, it is bound to a pretty strict
rendering. It's fun to have it in 3D but I'm not sure if, say, rotating
it or changing lighting would still make it the same logo.
